This page bundles the available data for the Volga-Ural Basin
in the Greater Caspian Region. The
images are hyperlinks and will open up a separate window with a high
resolution PDF image of the map.
The basin data is derived from a lower resolution grid which has been upsampled
using GMT. This could have
introduced an accuracy which is beyond the original data resolution.

Basin cross section

The basin cross section is automatically generated using the available
crustal structure data sets. Sometimes the data labels are not plotted
correctly, depending on the length of the section.

The location of the profile is indicated in all maps as dashed-dotted
thin black line. For the endpoints of the profile, the two points of
a given polygon located farthest away from each other were computed.

The dynamic topography history for the basin is derived by tracking the
basin centroid. The paleo-location for this point
is computed using the EarthByte plate kinematic framework
rotating the position back in time.

The dynamic topography model is derived from the S20RTS seismic tomography model
(Ritsema et al., 99) by converting seismic velocites to density anomalies
using an empirical scaling factor of 0.25. The density anomalies are then advected back
in time to compute mantle flow with plate motions superimposed (using the
EarthByte plate rotation framework)
as surface boundary conditions. The dynamic topography is then derived from the
computed density distribution using a free upper boundary. For details regarding the
methodology see the following papers:
